Lastnight i was leaving work and my truck all the sudden started running horribly. Sounded like a few cyl werent running. Well it went away so i shut my truck off and looked under the hood. Wighled all the injector harmess conectors and. Continued on my way without a problem. Today on my way to work it happened again. But only goes away randomly for about 30 seconds. Only thing i have done to the truck recently is put on a new exhaust ( 5 days ago) and put a new fuel filter on ( two days ago).

Any ideas or tips would be great as i would like drive back to my parents house tonight when i get off work for the holidays.

This truck has always ran great. Never any major problems. Now its running horribly and im stumped as to why.

The fuel heater element may be loose and shorting out on the side of fuel bowl,which in turns shorts the pcm,a full short blows#22 fuse creating a no start.I mention this first due to recent fuel filter change.Secondly your post "Check engine light" CEL could be most likely the CPS,it sounds similiar to what happened to me a few weeks back,random miss,and mine would cut off.not fun.Third and last, injector harnesses.And you can get it scanned for codes if you are so inclined.

Ok so I rePlaced the cps. The truck now rund fine unless i try to accelerate any faster than granny shifting. Even with granny shifting. The ce light will come on every 15 miles or so and it will run like crap
So ill shut it off and immedately start it And its fine for a few more miles then repeat.
Also it seems to mess up more often the closer to 2000 rpm's i
Get
Any idea as to what it could be?

harnesses, check them all. did it sound like only one bank was running?

Yes it sounds like a few arent hitting. I checked the harness and the furthest foward pin on the driver side is melted off the harness and to the connector. (if im not mistaken this pin controls the glowplug so it shouldnt mess with the injector? ). So i pulled the driver side valve cover and the harness under there looks fine .
